Definitions

  • the present invention relates to valve assemblies and, more particularly but not exclusively, to valve assemblies for insertion in floor drains.
  • the drain will include a pipe that extends through the floor with the upper end of the pipe being provided with a floor waste.
  • the floor waste includes a tubular portion that projects into the pipe and an upper grid or grate that is generally located at floor level and through which water enters the tubular portion for delivery to the pipe.
  • the pipe at a position slightly below the floor waste may have an "S" bend which retains water to prevent gases passing up through the pipe to exit via the floor waste into the room.
  • Document WO 03/097949 A1 discloses a floor drain valve assembly having the features of the preamble of claim 1. According to the invention a valve assembly with the features of claim 1 is provided. Preferably, the resilient means as defined in claim 1 is a spring.
  • a floor waste including the tubular member into which the valve assembly of claim 1 is sealingly inserted, the tubular member having an upper end and a lower end, and a grate secured to the upper end beneath which the valve assembly is located.
  • FIG. 1 to 3 illustrate a preferred valve assembly 10.
  • the valve assembly 10 is inserted in a floor waste 11 that is mounted within a drain pipe 12 secured within a floor of a room in a building.
  • the pipe 12 leads to an "S" bend connected to the sewerage system.
  • the pipe 12 is circular in transverse cross-section and has an internal cylindrical surface 13.
  • the floor waste 11 includes a tubular member 14 that is of circular transverse cross-section so as to have a generally cylindrical outer surface 15 and a generally cylindrical inner surface 16.
  • the surface 13 surrounds a passage 17 and the cylindrical surface 16 surrounds a passage 18.
  • the passages 17 and 18 have a common longitudinal axis 19.
  • the surface 15 has an annular groove 20 within which a seal 21 is located.
  • the seal 21 is of resilient material such as plastics and/or rubber. The seal 21 sealingly connects the surfaces 13 and 15.
  • the tubular member 14 Fixed to the upper end of the tubular member 14 is an outwardly extending flange 22 that provides a lip upon which there is mounted a grate 23.
  • the grate 23 has a plurality of passages 24 through which water may pass.
  • the valve assembly 10 includes a tubular body 25.
  • the body 25 is of a generally circular transverse cross-section so as to provide a generally cylindrical outer surface 26 and inner surface 27.
  • the surface 26 has an annular groove 28 within which is mounted a seal 29.
  • the seal 29 is formed of resilient material such as plastics and/or rubber and is compressed against the surface 16 so as to sealingly connect the tubular body 25 and the tubular member 14.
  • the surface 27 surrounds a passage 30 also having the longitudinal axis 19.
  • the body 25 is formed with a mounting arrangement 31.
  • the mounting arrangement 31 co-operates with a pivot assembly 32 supporting a movable valve member 33 for pivoting or angular movement about a generally horizontal axis 36, that is an axis generally transverse to the axis 19 but displaced therefrom.
  • a resilient means in the form of a spring 34 extends between the valve member 33 and mounting arrangement 31 to urge the valve member 33 to engage a valve seat 35 of the body 25.
  • An alternative resilient means may additionally comprise a counter-weight, or in a not claimed embodiment, the valve member itself may be counterweighted to perform the same function.
  • the seat 35 is provided at the underside of an annular flange 37 fixed to the tubular body 25.
  • valve member 33 In operation of the above described valve assembly 10, when water passes through the passages 24 and rests on the valve member 33, pressure is applied to the valve member 33. When the pressure exceeds a predetermined pressure, the valve member 33 is moved away from the seat 35 to an open position permitting the water to pass through the passage 30 to enter the passage 18 and then the passage 17. When no such water is present, the valve member 33 is engaged with the seat 35 to prevent gasses, including odour causing air, passing from the passage 17 to the passages 24.
  • tubular member 14 of the floor waste 11, the tubular body 25 of the valve assembly 10, and the grate 23 are moulded from plastics material.
  • the floor waste 11 When assembling, the floor waste 11 is inserted in the pipe 12 by sliding the seal 21 down the surface 13.
  • the valve assembly 10 is inserted in the floor waste 11 by sliding the seal 29 down the surface 16 and then locating the grate 23 on the flange 22.
  • valve assembly 40 is illustrated in Figs. 4 to 6 .
  • the valve assembly 40 is, in use, inserted in a floor waste that is mounted within a drain pipe of a floor of a room in a building in the manner as described above with reference to the valve assembly 10.
  • the valve assembly 40 has a tubular body 42 which is of a generally circular transverse cross-section so as to provide a generally cylindrical outer surface 44 and inner surface 46.
  • the outer surface 44 has an annular groove 48 within which is mounted a seal 50.
  • the seal 50 is formed of resilient material and is compressed against an inner surface of the floor waste so as to sealingly connect the tubular body 42 and the generally cylindrical inner surface of the floor waste.
  • annular flange 51 which provides a valve seat 52.
  • the inner surface 46 of the body 42 is formed with a pair of oppositely disposed guide slots 54 to engage correspondingly positioned guide members 56 formed on the annular flange 51.
  • the guide members 56 engage the guide slots 54 by an insert and twist locking action.
  • the annular flange 51 is formed with a mounting arrangement comprising a mounting block 58 and a pair of mounting stems 59.
  • the mounting block 58 co-operates with a pivot assembly 60 supporting a movable valve member 62 for pivoting or angular movement about a generally horizontal axis 64.
  • the axis 64 is an axis generally transverse to, but disposed from, a common vertical axis through the central passages of the floor waste and the drain pipe.
  • the pivot assembly 60 includes a pivot rod 66, clamp bracket 68 and clamp screw 70, with the pivot rod 66 engaged at its opposite ends through a pair of pivot rings 72 formed on the movable valve member 62. A middle portion of the pivot rod 66 is engaged to a pivot flange 73 of the valve member 62 via the clamp bracket 68 and clamp screw 70.
  • the separate components 68, 70 may be in a single moulded form.
  • a resilient spring 74 extends between the underside of the valve member 62 and a mounting stem 59 extending downwardly from the annular flange 51 to urge the valve member 62 to engage the valve seat 52.
  • the valve seat 52 includes a seal 78 to sealingly connect the valve member 62 and the annular flange 51, thereby closing the passage through the floor waste.
  • valve member 62 In use, when water flows onto the valve member 62 and applies a pressure thereon that exceeds a predetermined pressure based, at least in part, on the nature of the spring 74, the valve member 62 is moved away from the seat 52 to an open position permitting the water to pass through the passages of the floor waste and drain pipe. When no such water is present, the valve member 62 is engaged with the valve seat 52 to advantageously prevent gases, including foul air, passing up through those passages into the room.
  • Yet another advantage of the invention resides in its ability to be retrofitted or installed in most existing floor drains without having to replace, or cause damage to, the grate, grate mounting flange, surrounding floor surfaces, or pipes.
